Analyst Anthony P. Gallo said, "We see increased competition in truck brokerage and subsequent pricing pressure leading to margin headwinds and less earnings growth. We also see some âspilloverâ into intermodal. In truck brokerage, we believe large players are more interested in growth and market share gains versus near-term earnings. We think these dynamics and other factors will in turn keep a lid on intermodal rates even as rail cost inflation continues."
